Abstract

A system and method for organizing a non-volatile memory is disclosed. The system includes a non-volatile memory with a first data region and a first redundant memory area associated with the first data region. The first redundant memory area includes a first portion associated with a first data sector. The first portion of the redundant memory area includes a relative sector index and a block number. The redundant memory area also includes a second portion including error correction code (ECC) data.
